Hook up your phone to your computer, after you've downloaded and installed the "Samsung USB Drivers for Mobile Phones.exe". Download adb.exe and call it from your command prompt/console, like this:

Code:

cd c:\adb-fastboot
adb devices

If it shows a device with a long ID attached to it, you're in luck!

If you are rooted, you can bypass the screen lock.
If you are not rooted, you can still copy your photos.

To get the photos, use the ls command and adb pull to browse through your device and copy files and pictures back to your computer.

You can also use "adb backup" to retrieve all files, all app data, and even apks from the phone.

If you don't have the long ID, try rebooting to recovery mode and run "adb devices" again. Otherwise try another computer.

To bypass the lockscreen, use this command:

Code:

adb shell
rm /data/system/gesture.key

If you still can't get your device to recognize (USB Debugging disabled), you're still in luck if you have a Google account linked on the phone and an Internet connection. Download app ID "io.gillion.lockedphonebackup" to your phone from Play Store desktop site to transfer your pictures to external storage. You'll need your notification drawer accessible I believe.
